(4502) Vacuum pump
1 - A pump for creating a partial vacuum in a closed space. 2 - A pump where water is forced up a pipe by the difference in pressure between the atmosphere and a partial vacuum. 3 - An air compressor used in connection with steam condensers for improving the suction head on other pumps; the compressor takes its suction at low absolute pressure, compresses through a large number of compressions, and generally discharges at atmospheric pressure.
